why does the west wind drift flow to the east

Why Does The West Wind Drift Flow To The East?

The West Wind Drift flows east. It is a cold current. What causes currents such as the Kuroshio Current and the North Pacific Drift to flow in curved patterns? The water being colder affects the way that the currents flow.

Is the West Wind Drift warm or cold current?

f) Major currents of the Indian Ocean are West Australian (cold), and Agulhas Current (warm). g) The chief current surrounding Antarctica is the West Wind Drift (cold).

Why is the West Wind Drift the largest volume current in the world?

Also called the ‘West Wind Drift’ because it is driven by powerful westerly winds north of Antarctica. This current continues eastward encircling Antarctica without changing direction. It is the largest volume current in all the oceans.

Is the West Wind Drift fast or slow?

The average wind speed between 40°S and 60°S is 15 to 24 knots with strongest winds typically between 45°S and 55°S. Historically, the ACC has been referred to as the ‘West Wind Drift’ because the prevailing westerly wind and current are both eastward.

What causes the West Wind Drift?

a current in the southern hemisphere moving from west to east at approximately 40°-55°S, caused by prevailing western winds. Along the northern and southern borders of the West Wind Drift, formed by zones of convergence of surface currents, large masses of floating algae accumulate in certain areas. …

In which direction does the Benguela current run?

Benguela Current, oceanic current that is a branch of the West Wind Drift of the Southern Hemisphere. It flows northward in the South Atlantic Ocean along the west coast of southern Africa nearly to the Equator before merging with the westward-flowing Atlantic South Equatorial Current.

What are equatorial waters?

The water mass of the permanent or oceanic thermocline (100–600 m) in the tropical Pacific from 20°S to 15°N. North Pacific Equatorial Water (NPEW) is found north of the equator; it is formed by subsurface mixing between SPEW and central water. …

What is the world’s largest wind driven current that circles the continent?

The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times the volume of water flowing in all of the world’s rivers.

Is the West Wind Drift deep or shallow?

The West Wind Drift flows east toward South America south of latitude 40° S, and while most of it continues through the Drake Passage around the southern tip of South America to the Atlantic, a shallow stream turns north to parallel the continent as far as latitude 4° S, where it turns west to join the Pacific South …

What type of current is the West Australian Current?

The West Australian Current (or the Western Australian Current), is a cool surface current of the Southern Ocean and Southern Indian Ocean. It starts as the Southern Indian Ocean Current, a part of the larger Antarctic Circumpolar Current (also known as the West Wind Drift).

Is the Labrador Current fast or slow?

Speeds for the Labrador Current are about 0.3-0.5 ms-1 along the shelf edge (Greenbergand Petrie, Reynaud et al, 1985. Current speeds of 0.3-0.5 ms-1 were found by Reynaud et al. (1995) for the Labrador Current.

Is the California Current warm or cold?

The California Current is a cold water Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Sur.

Is the California Current fast or slow?

Schwartzlose: The average speed of the general California Current is about 4 to 4 knot (12.5-25 cm/sec) .

Where is the east wind drift?

Antarctic Coastal

The Antarctic Coastal Current, also known as the East Wind Drift Current, is the southernmost current in the world. This current is the counter-current of the largest ocean current in the world, Antarctic Circumpolar Current. On the average, it flows westward and parallel to the Antarctic coastline.

What is special about the West Wind Drift current?

Antarctic Circumpolar Current(West Wind Drift) The largest and most important ocean current in the southern hemisphere. It flows in an eastward direction around Antarctica, and occupies a wide tract of water in the South Pacific, South Atlantic, and Indian Oceans.

Is the ACC is the weakest ocean current on our planet?

The Antarctic Circumpolar Current, or ACC, is the strongest ocean current on our planet. It extends from the sea surface to the bottom of the ocean, and encircles Antarctica.

What cools current circles entire earth?

You can see on the map of the major surface ocean currents that the surface ocean currents create loops called gyres (Figure below). The Antarctic Circumpolar Current is unique because it travels uninhibited around the globe. Why is it the only current to go all the way around? The ocean gyres.

Why is the current cold on the west coast of southern Africa and warm on the East coast?

The Agulhas Current is formed by the confluence of the warm Mozambique and East Madagascar Currents, which meet south-west of Madagascar (not shown in the diagram). The cold Benguela Current originates from upwelling of water from the cold depths of the Atlantic Ocean against the west coast of the continent.

Why is the Mozambique current warm?

Agulhas Current

It flows southward along the southeast coast of Mozambique and the coast of South Africa before turning eastward to join the flow from Africa to Australia. … Because it is fed from lower latitudes, the Agulhas Current is warm, ranging in temperature from 57 to 79 °F (14 to 26 °C) at the surface.

Why does equatorial counter current flow from west to east?

This is will decided by the direction of Earth’s rotation. Earth rotates from west to east, so the piled up water due to earth’s rotation will come down on its eastern side and will thus flow in the eastward direction.

Why there is counter equatorial current?

Theoretical Background. The NECC is a direct response to the meridional changes in the coriolis parameter and the wind stress curl near the Intertropical Convergence Zone (ITCZ). In part the NECC owes its existence to the fact that the ITCZ is not located at the equator, rather several degrees of latitude to the north.

Which is the current of Pacific Ocean?

The North Pacific Current (sometimes referred to as the North Pacific Drift) is a slow warm water current that flows west-to-east between 30 and 50 degrees north in the Pacific Ocean. The current forms the southern part of the North Pacific Subpolar Gyre and the northern part of the North Pacific Subtropical Gyre.

Why is the North Pacific gyre important?

This gyre covers most of the northern Pacific Ocean. It is the largest ecosystem on Earth, located between the equator and 50° N latitude, and comprising 20 million square kilometers. … It is the site of an unusually intense collection of man-made marine debris, known as the Great Pacific Garbage Patch.

What was Antarctica called in the past?

Terra Australis
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.

Why do the North Pacific and North Atlantic gyres rotate clockwise?

Three forces cause the circulation of a gyre: global wind patterns, Earth’s rotation, and Earth’s landmasses. Wind drags on the ocean surface, causing water to move in the direction the wind is blowing. … In the Northern Hemisphere, ocean currents are deflected to the right, in a clockwise motion.

At what latitude is the ACC found?

The Antarctic Circumpolar Current spans 8° of latitude or more, and its course varies slightly by location. In the Pacific and Indian oceans, its northern boundary occurs between latitudes 48° S and 58° S, and its southern extreme approaches 70° S, near the coast of Marie Byrd Land in Antarctica.

What keeps Antarctica cold and icy?

Antarctica has a larger ice sheet

Ice is cold, and Antarctica is covered by the largest ice sheet on earth. The bright, white surface of the ice sheet reflects most of the solar radiation (and heat) that reaches it back to space. The ice also cools the air directly above it, helping to keep Antarctica cool.

How fast is the Alaska current?

Alaska Current

Flow velocities at a depth of 16 feet (5 m) have been reported to be as high as 1.7 knots (1.9 miles per hour) for the southern portion of the current. Volume transport is estimated to be in the range of 350,000,000 to 700,000,000 cubic feet (10,000,000 to 20,000,000 cubic m) per second.

Where does West Australian current flow?

West Australian Current, relatively cold surface current of the southeast Indian Ocean, part of the general counterclockwise movement in the southern section of that ocean.

What is the new name of Australia?

The sovereign country Australia, formed in 1901 by the Federation of the six British colonies, is officially known as the Commonwealth of Australia, abbreviated within the Commonwealth of Australia Constitution Act and the Constitution of Australia to “the Commonwealth”.
